Retesting is the process of re-executing test cases that failed in the previous test cycle, while regression testing is the process of re-executing test cases to ensure that changes or fixes have not introduced new defects.

• Retesting focuses on the failed test cases from the previous test cycle.

• Regression testing focuses on ensuring that changes or fixes have not introduced new defects.

• Retesting is performed to validate that the reported defects have been fixed.

• Regression test...read more

Smoke testing is a type of software testing that checks the basic functionality of an application without going into details.

• It is a preliminary test to ensure that the critical functionalities of the application are working fine.

• It is usually performed after a new build is received or after a major change is made to the application.

• It is a quick and shallow test that helps to identify major issues early in the testing cycle.

• It is also known as Build Verification Testing (BVT...read more

The question asks to print the number with the highest frequency in an array of strings.

• Iterate through the array and count the frequency of each number using a hashmap

• Find the number with the highest frequency

• Print the number with the highest frequency

Defect tracking tool is used to track and manage defects found during testing.

• Defect tracking tool helps in identifying, reporting, and tracking defects in software.

• It helps in prioritizing and assigning defects to the respective team members.

• It also helps in monitoring the status of defects and their resolution.

• Examples of defect tracking tools are JIRA, Bugzilla, and HP ALM.

Print alternate numbers in a given array of strings

• Iterate through the array and print elements at even indices

• Use a loop to skip every other element while printing

Use a loop to iterate through the array and print even numbers.

• Iterate through the array using a loop

• Check if each element is an even number

• Print the even numbers

Cb in circuitsss is the base-collector capacitance in a transistor circuit.

• Cb is an important parameter in transistor circuit design.

• It represents the capacitance between the base and collector terminals of a transistor.

• It affects the high-frequency response and stability of the circuit.

• Cb can be minimized by using a smaller collector-base junction area.

• Examples of circuits where Cb is considered are amplifiers, oscillators, and RF circuits.

Use Java to find the second maximum value in a table

• Iterate through the table to find the maximum value

• Keep track of the maximum value and the second maximum value

• Handle edge cases like duplicates or empty tables

• Return the second maximum value

Microgrid is a localized group of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized grid.

• Microgrid is a small-scale power grid that can operate independently or in conjunction with the main power grid.

• It can include distributed energy resources like solar panels, wind turbines, and batteries.

• Microgrids are often used to increase energy reliability, reduce costs, and integrate renewable energy sources.

• As an elect...read more
